TYPE-WRITING MACHINE.

Specification of Letters Patent.

Patented J line 6, 1916; Divided and this application filed March 2,

1916; Serial No. 81,646.

To all whom it may concern Be it known that I, JACOB Fruit-11., citi zenof. the- United States, and resident of Kathe borouglrof Manhattan. cityof New York, in the county of New York and State of New York, haveinvented certain new and useful Improvements in Type-"rrtmg Machines, ofwhich the following is a specification. I

-My present invention relates to universal bar mechanisms fortypewriting'machines and its main object is to provide new and improvedmechanism of the character spec fied.

I To the above and other ends my present invention consists in thefeatures of construction', combinations of devices and arrangements ofparts hereinafter described and particularly pointed out in the claims.

The present application is a division'of my .prior application, SerialX0. 58,821, filed October 30, 1915.

. In the accompanying drawings, Figure 1 is. a' vertical transversesectionalview of a typewrit'ing machine embodying my invention", partsbeingomitted. F ig. 2 is.a fragmentary' perspective view showing theuniversal bar mechanism and associate parts. Fig.3 is a fragmentary planv ew of the universal bar mechanism. Fig. 4 is a fragmentary perspectiveview of a modification.v

The machinelto which my invention is shown applied generally resemblesthe -"Monarch typewriting machine bat differing "infdeta-ils therefrom,and'comprises a mainj frame which is composed of a base 1, posts 2 and atopplate 3, above which is mounted a s lidable platen 4 that is drawnleftwardbyaspring drum mechanism of ordinary "movement being controlledby escapement devices, which comprise a toothed escape-l ment wheel ,5.Cooperative with the escape I ment wheel areescapement dogs 6 and 7construction (not shown); the leftward mounted at the top of, a carrieror rocker 8. The'dogs are or may be of the usual Mon; arch constructionbut in this instance they are reversed from the ordinary'arrange' Yment, that is, the rear dog 6 is the stepping or loose dog and theforward dog 7 the fixed 'dog. The carrier 8 is rocked or swung towardtherear and then forward again to produce step-by-step feed movements ofthe carriage by' universal bar mechanism of novel construction scribed.

Cooperative with the front face of the platen 1 are a circularlyarranged series of type bars 9, each typebar having fixed at its free-end a block provided with two types, the outer type 10 being the lowercase type to be hereinafter deand the inner type 11 being the upper casetype. The type bars may be pivoted on a common pivot wire 12'which ismounted on a shiftable type bar segment or element 13 in any well knownor desirable manner. The type bars fit in and are partly guided byconverging slots in the segment. Each type bar is connected by a link 14to an upright sub-lever 15 which is pivoted on a key lever 16, saidsub-lever being-slotted near its lower end to cooperate with a fixedabutment (not shown), butas usual in the Monarch machine. Near theirouter end portions the type bars are normally supported by a curved rest19 which as in the Monarch machine is mounted to shift with the type barsegment 13 during case shiftmg operations. The connections betweensaid'rest and the segment are however notherein illustrated. At itsopposite ends 'or sides said type bar segment is provided with groovedtrack portions 20 which receive anti-friction balls 21 that arecontrolled byseparators 22,. said balls also cooperating .withoppositely. grooved track ways 23 that are mounted on stationary posts24 rising from the base 1. For limiting up and down movements of thesegment along the station-- ary supports or posts, stop devices .are

provided comprising at' each side an upper stop 25 and a lower stop 26both on the segment itselfg. Cooperating stop. devices .27 and 28 areadjustably secured in pairs to the rear faces of the posts 24:. The ballbearing, mounting of the' segment and the:

' pivotally with pins 32 that extend latera" outward from the rear, freeends of crank arms33. The crank arms havefhubs 34 that fit over a keycontrolled rock shaft 35 and are fixed to' said rock shaft near itsends,

said rock shaft having stationary bearings. Outside each crank'arn'rthere is fixed to said rock shaft a forwardly extending crank arm.36. Fitting loosely' over the rock shaft inside each crank arm 36andextendstructed and operated as set-forth in my.

original application aforesaid. A depressionof either shift'key leveroperates on the underlying roll 39 to swing down the arms 37 and36,'rocking the shaft 35 and swinging the crank arm 33 upward. The

upward movement of the crank arms-33 is transmitted through the arms 30to the type bar. sup port comprising the segment 13, which support isthereby shifted or raised to an extent limited by the engagement of "thestops 26 with their associated stops 28.

The result of this shifting movement is to render the upper case types'11 operative when the type bars are actuated, the types 10 having beenshifted upward so that they willnot strike against the platen. lVhen theactuated shift key is released the type bar segment and connected'partsare re stored to normal position where the stops 25 engage with theirassociated stops 27. Counterbalancing springs and shift lockingdevicesas disclosed in my aforesaid original application are preferablyprovided.

The universal bar. according to my pres ent invention, is mounted toreciprocate on a frame or support which in turn ismovably mounted on theframe o'f-the machine or a stationary part thereof so that saiduniversalbar support is entirely separate froin and independent of the caseshifting element or type bar support 13. In the present instance theuniversal bar support is adapt ed to beshifted at times automaticallyupon actuation of rather one of the shift keys 40, and means are also )1';-\'l(l(l for disconnecting the universal. bar and its support so thatthe case shifting: keys will be ineffective on the universal bar, whichat such times will remain. in lower case position both when the type.bar segment is in lower case position. and also when said type barsegment is shifted to upper case position.

The throwing of the universal bar out of the control of: the shift keysand its restora-' tion to such control is preferably effected at willthrough the actuation of a special key. The supporting frame for theuniversal bar in the present instance comprises an upright segmentalplate or body portion ll.

haisan ear 6O perforated to receive which is adapted to fit into thecurv in'g above the type bar pivots. is provided with "straight, lateraleater 42w hich terminate in forwardly curved U 43 in \vhichare fixeddownwardly extending pins or hearing devices as. Fixed. to and extendingrearward from the plate near its middle is a bearing rod 45 terminatingin a head 46 while smallb'earing pins or devices 47 project rearwardfrom said plate near its ends. The rod 45 and pins 47 provide bearingsfor a slidable universal bar frame, designated as a whole bythereferencenumeral t8 and comprising a cross bar or $01- tion 49 provided with acentral depression 50 to afford play to the ribbon vibrator (not shown).Fixed to and extending real ward and inward from the cross portion areangular branches 51 and 52 which unite in a rearwardly extending stem 53p with a bearing block 5t that fits o slides on the rod 45. Upright earsat the ends of the cross bar 49 are perforated to fit; over the guidepins 4?. The end portionsof the crossbar are also provided with upwardlyextending ears 49 to which are fixed a universal bar proper 56, said unrversal bar being arcuate-in shape and be ing arranged close tothe edgeof the sup porting plate or frame 41. Said universal bar is providedwith an upturned ledge or lip which is adapted to be actuated directlyby shoulders 9 on the type bars The universal bar'is normally maintainedforward with the ears 55in contact with the rear face of the plate 41 bya coiled spring 57 which is connected at its rear endto the universalbar frame and at its front is in'chored to said lilate. Movements theiiniversal bar when actuated are limited by the head 46.

i To support and guide the frame 42 and the universal bar devicescarried said frame, a pair of brackets 58 are provid d. one secured toeach of the posts 2 1 at per front side by screws 59.

As a result of this reciprocation of the:escapement devices the carriagev will advance a letter space distancetoward the left under the pull of the spring drum or motor. A centertype guide 63 of ordinary construction is fixedto the universal barsupporting frame 41, 42 and shifts therewith. The type end of each typebar cooperates with said guide near the end of its stroke and at theprinting moment.

The meansfor automatically shifting the universal bar when the caseshifting mechanism'is operated by one of the shift key levers 40comprise connections between the support or frame 41, 42, and the rockshaft 35. Said connections include upright arms 64 pivotally connectedby shoulder screws 65 to the side portions 42 of the supporting frame.formed with. eyes which receive flanged bearing'blocksi66 that are heldin place by caps 67.. These bearing blocks are provided with downwardlyextending lugs 68 having rounded heads .gnd said bearing blocks 66 areperforated to fit loosely over the pins oistuds 32 outside the arms 30.Stationary pins or rods 70 fixed to the sides of the base and projectinglaterally inward therefrom in register with or in line with the studs32' terminate just short of the bearing blocks 66 so as not. tointerferewith the up and down movements of said bearing blocks when the rockshaft 35 is rocked. These rods 70 are of the same diameter as the studs32 and are adaptedjto receive and support the bearing blocks when thelatter are slid outward by means presently to be described for thepurpose of disconnecting the universal bar from the case shiftingmechanism. The ends of the studs 32 and of the rod 70 are preferablybeveled or tapered slightly to facilitate the lateral connecting anddisconnecting movements of the hearing blocks and the arms 64. whichcarry them.

The disconnecting means comprise levers 71 and 72 pivoted at 73 onangular brackets connected by a link or rod 83. The con- The lowerendsof the arms 64 are disposed at the right-hand sideof the keyboard? Theleft-hand lever 72 is substantially upright, comprising an upper slottedarm 81 which loosely engages wlth the lefthand lug 68, said leverfurther comprising a downwardlyextending arm 82.

. The lever'arrhs 75 and 82 are operatively '85 struction is such thatwhen the special key 80 is operated the extension 78, acting against thearm7 7, will rock the-bell crank 71 and through the rod 83 will alsorock the lever 72. The upwardly extending. arms of said lever will swingoutward away from each other and will act to shift the bearing blocks 66laterally outwardon to the stationary pins 70, thus disconnecting thearms 64 from the studs 32 as illustrated by 9 dotted lines in Fig. 1.Following such dis connection it will be understood that anoperation ofeither of the shift key levers 40 will be efl'ectiveto shift the typebar segment 13 but not the universal bar 56'nor its carrier frame 48,these parts remainlng down 1n lower case position. In order to reconnectthe disconnected parts, means are provided comprising a sleeve 84 thatis slidably mounted on the left-hand rod 70.. Connected with the sleeveor slide 8'1: is a push rod 85 that passes loosely throughan opening 86in the left-hand side'of the base I ing in the key 87 at this time thesleeve will contact with the left-hand bearing'block 129 and force itback on to its stud- 32. This; movement of saidbearing. block operatesthrough its lug 68 on a train of devices comprising the lever 72,.rod orlink 83and lever 71' to restore the right-hand bearing block 66 toengagement with its stud'32. On releasing the key 87 the spring 88 will,restore the sleeve to its left-hand positions step device 90 may beprovided forlim-.

v connected and which' it controls.

, simultaneously with said element to change Av modification oftheconstruction is illustrated in Fig. 4 wherein the leve'r'79 isreplaced by 'a lever 9% pivoted at the rear of the base and providedwith the usual restoring spring and finger key. Said lever 914 isprovided with a down'ward extension 95 which at its lower end is formedwith a slot indicated at 96 in which is loosely en-. gaged the lever arm77. lien the special 'key lever 9i is depressed the top of the slot 96engages with the lever arm to rock it and swing the rightliand bearingblock. 66

on to its rod 70. At the same time through the link 83 the him-=72 iscaused tos'wing the left-hand bearing block to its inopera tire positionon its rod 70. lVh-ile the lever 9-1 is maintained depressed by 'onefinger,

the-operator may, with the finger of the same-hand, depress theright-hand shift key 40 wh ch is in juxtaposition to the key of thelever 9%; This leaves the left-hand free to operate the printing keys.On releasing the key lever 94 its spring will re- .store it to normalposition and the bottom of the" slot 96 engaging with the under side ofthe lever .arm 77 will operate on the train of devices connected withsaid lever arm to restore the bearing blocks to engage-. ment with theirstuds. a Y I Preferably the special key lever 9lisprovided with alocking key of suitable construction, such as that found on the lefthand shift key lever of the X0. 10 Remington machine, by which lockingkey 'said special lever may be locked downto maintain the universal bar56 withdrawn from 'the control of the shift key mechanism as long as maybe desired.

It will be observed that the center-guide 63 is supported independentlyof the case shifting element. type bar, support or segment 13; that saidcenter guide is shiftable case position: that said center guide is alsoshiftable. independently of said element; and that said center guide andthe support on which it is mounted, hich is-alsothe support of theuniversal bar, are shiftable from upper case to lower. case positionwhile said element or type bar support remains quiescent.
